Backing Up and Restoring Mobility Services Engine Data This section describes how to back up and restore mobility services engine data. It also describes how to enable automatic backup. 2 OL

3 Backing Up Mobility Services Engine Historical Data This section contains the following topics: Backing Up Mobility Services Engine Historical Data, on page 3 Restoring Mobility Services Engine Historical Data, on page 3 Enabling Automatic Location Data Backup, on page 4 Downloading Software to the Mobility Services Engines, on page 5 Manually Downloading Software, on page 5 Backing Up Mobility Services Engine Historical Data Prime Infrastructure includes functionality for backing up mobility services engine data. To back up mobility services engine data, follow these steps: Choose Services > Mobility Services. Click the name of the mobility services engine that you want to back up. Choose System > Maintenance. Click Backup. Enter the name of the backup. Click Submit to back up the historical data to the hard drive of the server running Prime Infrastructure. The Status of the backup is visible on the page while the backup is in process. Three items appear in the page during the backup process: (1) Last Status text box that provides messages noting the status of the backup; (2) Progress text box that shows what percentage of the backup is complete; and (3) Started at text box that shows when the backup began noting date and time. You can run the backup process in the background while working on other mobility services engine operations in other the Prime Infrastructure page. Backups are stored in the FTP directory you specify during the Prime Infrastructure installation. Restoring Mobility Services Engine Historical Data You can use Prime Infrastructure to restore backed up historical data. To restore mobility services engine data, follow these steps: OL

4 Enabling Automatic Location Data Backup Before You Begin If configured for high availability, delete the secondary MSE before restoring historical data on the primary MSE. You can add the deleted MSE again after restoration on the primary MSE is completed successfully. Step 7 Step 8 Choose Services > Mobility Services. Click the name of the MSE that you want to restore. Choose System > Maintenance. Click Restore. Enter the FTP server address. Choose the file to restore from the drop-down list. Select the Delete synchronized service assignments check box if you want to permanently remove all service assignments from the MSE. This option is applicable for network designs, wired switches, Cisco WLCs, and event definitions. The existing location history data is retained, however, you must use manual service assignments to perform any future location calculations. Click Submit to start the restoration process. Click OK to confirm that you want to restore the data from the Prime Infrastructure server hard drive. When restoration is completed, Prime Infrastructure displays a message to that effect. You should not work on other MSE operations when the restore process is running. Enabling Automatic Location Data Backup You can configure Prime Infrastructure to perform automatic backups of location data on a regular basis. To enable automatic backup of location data on a mobility services engine, follow these steps: Choose Administration > Background Tasks. Select the Mobility Service Backup check box. From the Select a command drop-down list, choose Enable Task, and click Go. The backups are stored in the FTP directory that you specify during the Prime Infrastructure installation. 4 OL

5 Downloading Software to the Mobility Services Engines Downloading Software to the Mobility Services Engines To download software to a mobility services engine, follow these steps: Step 7 Step 8 Step 9 Verify that you can ping the mobility services engine from the Prime Infrastructure server or an external FTP server, whichever you are going to use for the application code download. Choose Services > Mobility Services Engine. Click the name of the MSE to which you want to download software. Choose System > Maintenance > Download Software from the left sidebar menu. To download software, do one of the following: To download software listed in the Prime Infrastructure directory, select the Select from uploaded images to transfer into the Server radio button. Choose a binary image from the drop-down list. Prime Infrastructure downloads the binary image to the FTP server directory you specified during the Prime Infrastructure installation. To use downloaded software available locally or over the network, select the Browse a new software image to transfer into the Server radio button, and click Choose File. Locate the file, and click Open. Click Download to send the software to the /opt/installers directory on the MSE. After the image is transferred to the MSE, log in to the MSE command-line interface. Run the installer image from the /opt/installers directory by entering the./.bin mse image command. This installs the software. To run the software, enter the /etc/init.d/msed start command. To stop the software, enter the /etc/init.d/msed stop command, and to check status, enter the /etc/init.d/msed status command. Manually Downloading Software If you do not want to automatically update the mobility services engine software using Prime Infrastructure, follow these steps to upgrade the software manually using a local (console) or remote (SSH) connection: Transfer the new MSE image onto the hard drive. a) Log in as root, and use the binary setting to send the image from an external FTP server root directory. The release note format is similar to the following and changes with each release: CISCO-MSE-L-K9-x-x-x-x-64bit.bin.tar.gz. The MSE image is compressed at this point. The default log in name for the FTP server is ftp-user. OL

6 Configuring the NTP Server Your entries should look like this example: #cd/opt/installers ftp <FTP Server IP address> Name:<login> Password: <password> binary get CISCO-MSE-L-K9-x-x-x-x-64bit.bin.tar.gz <CTRL-Z) # b) Verify that the image ( CISCO-MSE-L-K9-x-x-x-x-64bit.bin.tar.gz) is in the MSE /opt/installers directory. c) To decompress (unzip) the image file, enter the following command: tar zxvf CISCO-MSE-L-K9-x-x-x-x-64bit.bin.tar.gz The decompression yields 3 files : CISCO-MSE-L-K9-x-x-x-x-64bit.bin MSE_PUB.pem signhash.bin d) Make sure that the CISCO-MSE-L-K9-x-x-x-x-64bit.bin.tar.gz file has execute permissions for the root user. If not, enter the following command: chmod 755 CISCO-MSE-L-K9-x-x-x-x.bin Manually stop the MSE. Log in as root and enter the following command: /etc/init.d/msed stop To install the new MSE image, enter the following command: /opt/installers/cisco-mse-l-k9-x-x-x-x.bin Start the new MSE software by entering the following command: /etc/init.d/msed start Caution Only complete the next step that uninstalls the script files if the system instructs you to do so. Removing the files unnecessarily erases your historical data. Enter the following command to uninstall the script files of the MSE: /opt/mse/uninstall Configuring the NTP Server You can configure NTP servers to set up the time and date of the mobility services engine. MSE will support both IPv4 and IPv6 address configuration for the NTP server. You are automatically prompted to enable NTP and enter NTP server IP addresses as part of the automatic installation script for the mobility services engine. For more details on the automatic installation script, see the Cisco 3350 Mobility Services Engine Getting Started Guide or Cisco 3310 Mobility Services Engine Getting Started Guide at the following URL: installation_guides_list.html 6 OL

7 Resetting the System If you need to add or change an NTP server installation after a mobility services engine install, rerun the automatic installation script. You can configure the NTP server without adjusting the other values by tabbing through the script. For more information on NTP server configuration, consult the Linux configuration guides. Resetting the System For information on rebooting or shutting down the mobility services engine hardware, see the Rebooting or Shutting Down a System. Clearing the Configuration File For information on clearing the configuration file, see the Clearing the System Database. Viewing the Log Files Log files helps you to troubleshoot and identify the issue. These log files display overall health of MSE and network configuration information. You can gather the log details using the MSE user interface or CLI. If you are unable to use the user interface to download the logs, you can alternatively use the CLI access to download these log files. Viewing the Log Files Using CLI To view the log files using CLI: Log in as root and enter the following command: Example: cd /opt/mse/logs To create a tar file for the logs, enter the following command. Example: tar -zcvf filename /opt/mse/logs All the log files are compressed to generate a tar achieve file. You can decompress (unzip) the file to view the log details. OL

8 Viewing the Log Files Using MSE User Interface Viewing the Log Files Using MSE User Interface To view the log files using MSE User Interface: Log in as root. Enter the FTP server address. Enter the username and password. Enter the name of the log file. The log files are displayed and you can compress them to a tar file. 8 OL
